    NAME
    grip - A gtk-based cd-player and cd-ripper.

    gcd - A gtk-based cd-player (used as part of grip, or alone).

    SYNOPSIS
    grip [-d ] [-s] [-l]

    gcd [-d ] [-f] [-l]

    DESCRIPTION
    Grip is a gtk-based cd-player and cd-ripper. It has the ripping
    capabilities of cdparanoia builtin, but can also use external rippers
    (such as cdda2wav). It also provides an automated frontend for MP3
    encoders, letting you take a disc and transform it easily straight into
    MP3s. The CDDB protocol is supported for retrieving track information
    from disc database servers. Grip works with DigitalDJ to provide a
    unified "computerized" version of your music collection. GCD is the cd-
    player only version of Grip.

    Because Grip and GCD share much of their functionality, this file
    documents both of them. If you installed only GCD, you should ignore
    the bits that talk about "ripping" and "encoding" of tracks.

    Grip is designed to work closely with DigitalDJ, my SQL-based mp3
    jukebox system (although it does not require it). DigitalDJ can be
    obtained from:

    http://www.nostatic.org/ddj(...)

    OPTIONS
    These are the command-line options for grip:

    -d
    Use as the cd-rom device (default: /dev/cdrom).

    -s Launch grip in a "small" (cd-only) mode.

    -l "local" mode -- don't try to use CDDB.

    -v Verbose (debug) mode.

    These are gcd's command-line options:

    -d
    Use as the cd-rom device (default: /dev/cdrom).

    -f Launch gcd in "full" (track-display) mode.

    -l "local" mode -- Don't try to use CDDB.

    -v Verbose (debug) mode.

    USAGE
    The most handy way to launch Grip/GCD is from your window manager's
    doc. A dock icon (gripicon.tif/gcdicon.tif) is included with the
    distribution.

    Grip's operation should be pretty self-explanatory. Tracks to rip are
    selected with the right mouse button. To select all tracks on the disc,
    click the "Rip" column label. When you select "Rip" or "MP3-encode"
    from the "Rip" page, Grip will rip or rip/encode the tracks you have
    selected. If you select "Rip partial track", only the current select of
    the current track will be ripped or encoded. Start/End sector values
    are ignored if partial track ripping is not enabled.

    Grip and GCD used to be installed as setuid root. This was for several
    reasons. First, most people have their systems configured such that
    their user account does not have access to the cd drive. Secondly,
    cdparanoia requires access to both the cd device and (for SCSI drives)
    the generic SCSI device (usually /dev/sg). Despite this, I
    no longer install the programs setuid root. This means that you will
    have to set the permissions correctly on the appropriate devices, or
    run the program as root.

    IMPORTANT!

    If you have trouble with Grip or GCD, read the "Common Questions"
    section. I'm getting bogged down in email these days. This being said,
    I do appreciate feedback on Grip. If, after reading through this
    document carefully, you still have a question, or have a feature
    request, feel free to email me. Do read the file TODO first, however,
    to check whether it's already on my list.

    IMPORTANT!

    CONFIGURATION
    The "Config" menu allows you to configure your ripping program and your
    CDDB database. Rip/Encode/ID3 options are only available in Grip.

    Here are the options:

    CD options:

    Don't interrupt playback on exit/startup
    If this is not selected, Grip will stop play when it starts and
    when it stops.

    Rewind when stopped
    If selected, Grip will rewind to the first track when play is
    stopped.

    Startup with first track if not playing
    If this is not selected, Grip will begin with whatever track the
    cd-player played last.

    Reshuffle before each playback
    If selected, Grip will re-randomize the tracks each time playback
    begins when in shuffle-play mode.

    Rip Options:

    Ripper
    This allows you to select one of the preset rippers. This will
    fill in sensible default parameters for calling the ripper. If you
    select "grip (cdparanoia)", Grip will use its builtin version of
    cdparanoia (only available if paranoia has been compiled in). If
    the builtin ripper is selected, the following options are
    available:

    Disable paranoia
    Disables all paranoia checking.

    Disable extra paranoia
    Only cdda2wav-style overlap checking will be done.

    Disable scratch detection
    Do not look for scratches.

    Disable scratch repair
    Disable scratch repair (still detect)

    Ripping executable
    This should be the full path to the program you want to use to rip
    tracks with.

    Ripping command-line
    These are the arguments that will be passed to the ripping
    program. The '%' switches are translated as follows:

    %t Track to be ripped

    %b Begin sector to be ripped (0 is start of track)

    %e End sector of track

    %f Filename to put .wav data to

    Rip file format
    This specifies the format of the filename to write ripped data to.
    The '%' switches are translated as follows:

    %n Name of track being ripped

    %t Number of track being ripped

    %a Artist of current track

    %A Artist of the current disc

    %d Name of current disc

    %b Begin sector to be ripped (0 is start of track)

    %e End sector of track

    %c cdrom device

    %i CDDB discid in hex format

    %g ID3 genre tag as a number

    %G ID3 genre tag as a word

    Adding a '*' between the '%' and the switch will cause
    underscoring of the field to be skipped.

    Rip 'nice' value
    The 'nice' (priority) level to run the rip at.

    Max non-encoded .wav's
    The maximum number of non-encoded .wav files grip will keep around
    before pausing ripping.

    Auto-rip on insert
    If selected, Grip will automatically select all tracks and begin
    ripping when a new (ie: no local disc data) disc is inserted.

    Auto-eject after rip
    If selected, Grip will automatically eject the disc when ripping
    is finished.

    Wav filter command
    This command will be run after ripping but before encoding. It can
    be used to call a program to manipulate the .wav file in some way
    (such as doing normalization). It accepts a single switch, %f,
    which translates as the ripped .wav file.

    MP3 options:

    Encoder
    This allows you to select one of the preset rippers. This will
    fill in sensible default parameters for calling the encoder.

    MP3 executable
    This should be the full path to the program you want to use to
    MP3-encode tracks with.

    MP3 command-line
    These are the arguments that will be passed to the MP3 encoder.
    The '%' switches are translated as follows:

    %b Encode bitrate (kbits/sec)

    %f Filename of the .wav data to be encoded

    %o Filename to save mp3 data to

    MP3 file format
    This specifies the format of the filename to write MP3 data to.
    The '%' switches are the same as those used in the rip file
    format.

    Delete .wav after encoding?
    If selected, this option will (surprise!) delete the ripped .wav
    file after encoding.

    Insert into SQL database
    If selected, and DigitalDJ is installed, Grip will place the song
    information into DigitalDJ's song database.

    Number of CPUs to use
    This is the number of simultaneous encode

    processes allowed. If you have an SMP system, increase this number
    to use more processes. Note that Grip must be restarted for
    changes in this option to take effect.

    MP3 'nice' value
    The 'nice' (priority) level to run the MP3 encode at.

    ID3 options:

    ID3 Executable
    The full path to the program that will add ID3 tags to an MP3 file

    ID3 Command-line
    The arguments to be passed to the ID3 program. The % switches are
    translated as:

    %n Name of track

    %t Number of track

    %a Artist of current track

    %A Artist of the current disc

    %d Name of current disc

    %g ID3 genre tag as a number

    %G ID3 genre tag as a word

    %y Year of track

    %f Name of the MP3 file

    Add ID3 tags
    If selected this option will cause ID3 tags to be added to each
    MP3 file after it is encoded.

    CDDB options:

    Primary/Secondary CDDB server
    These are your servers for looking up disc information over the
    net. If the disc is not found on the primary server, the secondary
    server will be checked.

    DB server
    The address of the CDDB server you wish to use.

    DB CGI path
    The path to the script on the server that handles HTTP requests.
    This is generally "~cddb/cddb.cgi" or "cgi-bin/cddb.cgi".

    Perform CDDB lookup automatically
    If selected, Grip will always try to look up an unknown disc. If
    not selected, lookup must be initiated manually.

    Proxy options:

    Use proxy server
    If selected, CDDB requests will be sent through an HTTP proxy
    (useful for people behind firewalls).

    Get server from 'http_proxy' env. var:
    If set, Grip will try to read the http server/port information
    from the environment variable "http_proxy", which should take the
    form "http://server:port(...)".

    Proxy server
    The address of the HTTP proxy server to be used.

    Proxy port
    The port to talk to the proxy on.

    Misc options:

    Output directory
    The directory to place WAV and MP3 files in. The same '%' switches
    as in the rip/encode filenames can be used.

    Convert spaces to underscores
    If selected, this will cause all spaces in filenames to
    underscores.

    Also underscore
    A list of characters to replace with underscores when constructing
    filenames.

    Email address
    The email address to be used as a reply address when submitting
    CDDB entries and bug reports.

    CD update program
    This program will be run whenever a disc is put in the drive. All
    sensible '%' switches can be used. I use this to call a program
    that generates a web page that tells what CD I'm currently
    playing.

    Keep application minimum size
    If selected, Grip will always try to keep its window a the minimum
    size possible.

    Common Questions
    Q:
    When I try to rip a track, I get X I/O errors. What gives?

    A:
    This seems to be a problem with non-thread-safe systems. Make sure your
    system is safe for threads. This often seems to be associated with
    libc5.

    Q:
    I just get a message saying that the program can't access my drive.
    This makes it hard to do much. Help!

    A:
    Your user account must have access to the cd device. See the "Running
    Grip/GCD" section for more information on this.

    Q:
    I can play cd's fine, but my ripper can't access the drive. Why not?

    A:
    Rippers (cdparanoia, at least) need access to the generic SCSI device
    as well. See the "Running Grip/GCD" section for more information on
    this.

    Q:
    The progress bar doesn't seem to be completely accurate when doing an
    MP3 encode. Why can't it get it right?

    A:
    The progress bar is done based on the size of the output file. If you
    have the kbits/sec set properly, Grip should estimate the size
    properly. Note that if you use variable bitrate encoding (supported by
    encoders like LAME and xing) Grip has no way to accurately guess the
    file size.

    Q:
    I can't get lame to work. How lame is that?

    A:
    Lame has trouble with long filenames. If you increase MAX_NAME_SIZE in
    the common.h file of the lame source distribution, it works fine.

    Q:
    When I encode tracks, the MP3 progress bar never does anything. What
    happened to progress?

    A:
    If your MP3 encoder doesn't accept an output filename (like BladeEnc),
    or you haven't passed it one on the command-line, then it might not be
    outputting to the file Grip expects. Make sure that your MP3 file
    format is set to what your encoder is actually producing.

    Q:
    When Grip looks up disc information, it works, but says "Error saving
    disc data". Why?

    A:
    Grip saves local copies of disc track information in the directory
    "~/.cddb". It must be able to create or access this directory.

    Q:
    How come I don't get any scrollbars in the track display?

    A:
    You are using a version of Grip compiled for gtk+ v1.0.x on a system
    that has gtk+ v1.1.x installed. You need to either get a binary
    compiled for the development series of gtk+, or compile Grip yourself.

    Q:
    When my buddy runs Grip, he gets those nifty LCD icons showing
    rip/encode/CDDB status, but I don't. What makes him so special?

    A:
    He's using a more recent version of gtk+ than you are. Due to bugs in
    gtk+ v1.0.x, I don't support the icons under it. Upgrade your gtk+!

    Q:
    I can't get Grip to rip any tracks! This makes it less than useful...

    A:
    Grip won't rip tracks unless you tell it what to rip. Use the right
    mouse button to select tracks for ripping.

    Q:
    Grip just hangs when doing a CDDB lookup. Why?

    A:
    If you are using Linux kernel 2.2.x, you need to compile Grip from
    source. Installing the RPM results in network problems.

    Q:
    I was listening to a CD in Grip and it sounded horrible! What's up?

    A:
    Perhaps you are listening to country music...

    CDDB notes
    I have declined to sign a license agreement with Escient, the company
    who owns "www.cddb.com" and runs the CDDB server "us.cddb.com". Their
    license would (among other things) have required me to place
    advertisements in Grip and restrict you, the user, to use only their
    databases. I am against this commercial use of the track information
    submitted by users such as yourself. For this reason, I encourage you
    to use free servers, such as "freecddb.freecddb.org".
